PLEVA AF120 Measure Heads

PLEVA Material Moisture sensors

Sensoren voor het meten van de vochtigheid van materiaal bij bijv. impregneren, verven, coaten en drogen. Perfecte toepassing voor opbrengstmeting bij watergedragen processen.

Sensor principle:

Measurement of the material moisture is based on microwave absorption by water. A semiconductor oscillator transmits microwave energy through the web. The non-absorbed part of the energy is received on the opposite side by a microwave receiver. The amount of absorption is a measurement of the absolute moisture content.

Applications of static microwave heads:

PLEVA material moisture measuring units incorporating microwave technology are used to make on-line, contactfree, immediate, precise and non-destructive measuring of the moisture in planiform product. The measuring devices AF • RF are designed for the measurement of application of moisture on webs with fixed measuring heads. Fields of application are:

Textile industry Liquor pick-up on fabric webs Dyeings and wet-in-wet applications independent from sort of fibres and colour Latex- and foam-coating for carpets Applications at non wovens Filters Moisture at felts Water based coatings Minimal applications Tyre cords

Non-textile industries Paper, cardboard Adhesives Veneer panels Laminate boards Pluster boards Building boards Sausage casings Medical sector
